The frame A may be of'a rectangular-form, of stout wood, having across-beam, A, near the front, under the slides. The tongue 13 isattached to the hind part of the frame by a horiz'ontalpin, B, and itpasses through an open standard, ]3 ,on the front beam; whicharrangement allows the front of the machine to be raised or lowered, bymeans ofthe cam-level-B on the top of the tongue. In front, under thetongue, is a'roller, O, to regulate the depth to which the marker maygo. It may be placed higher or lower, by changing the pin in thestandard. i I V The wheels 0 and G are attached to the axle C, and turnwith it in bearings in or attached to the side beams, and should eachhave their circumference equal to the distance between the hills in arow, or equal to twice'or other convenient number of times suchdistance, as may be desired. And the distance between thewheelsshould-be double the distance of the rows apart. On the edges ofthe wheels are markers 0 C for marking the position of the hills. Thereshould be as many as the number of hills formed at each revolution ofthe wheels, and should be placed in such positions as that they willmark the ground directly opposite the hill.

The hoppers D and D are placed near the front of the machine. Theyshould be the distance apart from centre to centre it is desiredto placethe rows, and the wheels should be half that distance each fromitsadjacent hopper. Thus, if it is desired to plant the corn in rowsfour-feet apart, the hoppers should be four feet apart and the wheelseight feet apart from centre to centre; that is, two feet eaeh from thehopper on the same side. Eachhopper has a spout extending from thebottom to the ground I) and D. The slide D extends across the machineand is directly over the spouts. 'It has holes of different sizes soarranged that when one hole is over one spout, a corresponding one insize will be over the other spout, according to the size of the grain tobe sown, or the quantity to be dropped. This slide is held in place bythe spring-catch D Directly over D" is a similar slide, D, but havingonly one pair of holes, so arranged that when the machine is at rest theslide covers the bottom of the hoppers, and the holes are brought underthe hoppers only when the seed is to be passedout. D* has an arm, Dextending towards the front of the machine. Extending from the upperends of this arm, towards the other end of the machine, is a lever, E,which turns on a pin near its centre, and is connected with the arm D bya. pin, E The lower end of E is a cam, having a bevelled end and a notchat the end of the bevel On the axle G is a drum, in which are one ormore pins,- ac'cording to the number of hills to be made at eachrevolution of the wheels C and 0. They are marked 0 This drum is justunder the end-of E. As the drum turns with the wheels, the pin C strikesthe bevelled end of E, which presses the end of the'lever to the right,and of course the end attached to D to the left also, until it bringsthe holes therein, one each under the hoppers, when the grain will passout. When the pin 0 ha reached the notch Ehthe lever E is freed from thepressure of the pin 0 and the slide D is instantly drawn back by the rodD attached to the spring D.

Under E, and at right angles to it, is a spring, G, which raises Eabovethe pin 0 when it is not desired to have the slides move. At other timesE is pressed down, so that the pin C will catch it, by means of thecam-lever]? lying directly upon it. Attached to the rear end of theframe is a lever, H, having an upward spring, with a hole, H, in it,corresponding with a pin or pins, H on the drunu By depressing thislever with the foot, the hole catches the first pin H on the drumandlocks the wheels. These pins H should be equal in number to the pins 0and be arranged on the other end of the drum, at equal distances apart,a half, quarter, sixth, or the like, of the circumference from the pins0 respectively, according to their number.

On the front of the machine, and just before each spout, is a peculiarlyformed teeth, I, the lower part of which marks the ground for the corn,and the upper part clears away the stones, clods, or sods, so as toallow the covering-teeth to cover the seed properly. This marking partis of V-form, and of such width at its rear open end, and of thenecessary depth, to plant the corn properly. On this marking part is theclearing part, also of V-form but having inuchbroader wings, and havingits lower edge, which rests on the upper edge of the marking part,turned outward, I I

The covering-teeth K are formed with an inward slope at the lower'edge,towards the front, and a somewhat spoon form towards the centre, with aninward curve on the upper edge, towards the standard at the rear end, bymeans of which form the front under side will enter slightly the ground,and as it passes on will raise the loose earth up and turn it over uponthe planted seed. One of these teeth is placed near the spout on oneside of the hill, and the other behind it on the opposite side of thehill, at such distance apart in either direction as may be deemed mostsuitable to cover the seed and yet permit the stones to pass through.

The mode of operation is as follows: The seed is placed in the hoppers.The marking-teeth in front are regulated as to the proper depth by meansof the roller C in front. The maehine'is now started in the directionthe rows are to run, and the marking-tooth will form a furrow of thedesired depth and width, while the clearing part of the tooth removesfrom the surface along the furrows all stones, clods, sods, and thelike.

lhe first'hill may be formed at any desired point, by not pressing downthe cam-le'ver F, or by leaving the wheels locked, until the propertime, when the pin 0 in the drum will press the lever E to the right,and carry the slides D, by means of the connection, through the arm D",and pin E to the left, so that the holes therein come under the hoppers.This allows the seed to pass out through both slides and down thespouts. As the cam on E is short, the slide D is kept in such positiononly long enough to allow suflicient seed to pass out, when it isinstantly retracted by the spring Df, and the hopper is closed andremains so until the point is reached where another hill is to beformed, when the said pin 0 again moves the slide D, and the seed isagain dropped, and so on. The markers 0 on the wheels form a markopposite to each hill. As soon as the seed has been dropped and theground cleared by the clearing-tooth, the covering-teeth on each side ofthe rows raise a little of the earth ormould and turn it once on to thefurrow.

When the end of the row has been reached the front of the machine may beraised from the ground by the lever B and by pressing down, by the footof the operator,.the lever H, the pin H will enterthe hole 1-1, when thewheels will be locked, and the machine will cease to operate when it haspassed half the distance between the hills from the last hill. It maynow he slipped along to any-convenient distance, and then be turnedaround on the inside wheel asa centre, and then slipped forward untilthe spouts are on a line with where they were when the wheels werelocked, when the front may be lowered, the wheels unlocked, and then berun back over the field, the said wheel in the same track it made informing the first rows; the other wheel being new the inside one, andwhich will run back on its track for the next row. As the wheels arehalf the distance of the rows apart from the adjacent hoppers, it isobvious the running of tlie inside wheel back in the same track willcause the third row to be at the same distance from the second that thesecond is from the first, and so on until the work is done.

The hills may readily be kept in a line by starting right andkeeping'watch of the erossmarkings made byfi A seat may be placed overthe centre for the driver, and a roller maybe added if desired forcovering the seed, and the machine may be adapted to one or two horses.By adding other pins to the drum C, the hills may be as near together inthe rows as may be desired.

The advantage's of a machine so constructed are, it is simple and cheap,and of few parts, easily under stood and managed, and not liable to getout of order. It also dispenses with all marking but such as the machinemakes, while it clears the ground for the seed, and allows it to becovered in a proper manner.

Having thus described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is.-

1. The tooth I, constructed and operating substantially'as described forthe uses and purposes mentioned.

2. The said tooth I, and the teeth K K, one or more, in combination, forthe uses and purposes mentioned.

' 3. The adjustment of the wheels C G, and the hoppers D D, relative toeach other, as desdribed, by means of which the rows will be at equaldistances apart, as described.

4. The slide D, and the lever E, and spring D, and cam-lever F,constructed and operating in eombina tion, substantially as describedand for the uses and purposes mentioned.

5. The lever H,in combination with the pin. or pins H on the drum Csubstantially as described and for the uses and purposes mentioned.
